TooT-H-oAnnING DEVICE.

Application filed June 7,

T 0 all whom it may concern.

Be it known that I, LAFAYETTE Proms-1e ING, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Tooth-Carding Devices, of which the following is a specification.

The present invention is directed to improvements in carding device for artificial teeth.

One of the objects of the invention is to provide a carding device constructed and arranged so that the teeth may be quickly and easily mounted for convenience in handling, displaying and shipping.

A further object of the invention is to provide a device of this character so con structed that the teeth may be held firmly upon the carding device, but can be easily removed as desired, the construction for accomplishing this end being extremely simple, durable and efficient in operation.

With these and other objects in view, as will appear as the description proceeds, the invention consists in the novel features of construction, combinations of elements and arrangements of parts, and hereinafter to be fully described and pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a front elevation of the device,

Figure 2 is a transverse sectional view,

Figure 3 is a sectional view on line 33 of Figure 1, and

Figure 4: is a fragmentary plan elevation of a slightly modified form of the invention.

The device consists of a base 1. preferably rectangular in shape and formed from wood, or any other material desired. it being essential, however, that the material be such that the studs 2 can be driven therein for secure connection. These studs are arranged in spaced relation and have rounded heads 3 which are disposed transversely of the base 1.

An elongated metallic plate 4 is engaged with the base and is provided with slots 5 through which the studs 2 extend so that the heads 3 thereof will be above the plane of the plate. This plate is provided with a plurality of pairs of tongues 6 which are struck from the plate and extend trans- 1923. Serial No. 644,010.

versely thereof, said tongues being inclined upwardly to impart thereto the necessary resiliency for holding the teeth 7 firmly, yet readily capable of being removed or re placed. The tongues of each pair lie upon opposite sides of the studs so as to support the teeth evenly.

The teeth are provided upon their inner sides with longitudinal slots 8 which have one of their ends terminating at points short of the cutting edge of the teeth while the other ends thereof open at the opposite ends of said teeth. Theseslots are so formed as to open into relatively enlarged channels 9 which are shaped to correspond substantially to the contour of the heads 3 which slidably engage the channels, but are prevented from being withdrawn through the slots 8. It will be observed that the diameter of the heads 3 are such that they will rest upon diametrically opposite points on the side walls of the channels when pressure is exerted upon the inner faces of the teeth by the resilient tongue 6.

To secure the teeth to the base it is only necessary to place the open ends of the slots 8 adjacent the studs and upon sliding the teeth transversely of the base the studs and the heads will pass into the slots and channels and compress the tongues, and owing to the resiliency of the tongues they exercise an outward pressure upon the teeth, thereby holding the same firmly interlocked with the studs.

In the modified form of the invention as shown in Figure 4, the plate 4 is provided also with similarly shaped and secured studs 10, the tongues 11 being struck from the plate 4 and have integrally formed with their free ends spaced fingers 12 which span the studs, and since the tongues are resilient the fingers will exercise sufficient pressure on the inner faces of the teeth to firmly hold the same in place. It will be of course obvious that in both forms of the invention that upon reversing the movement of the teeth that they can be easily and quickly removed from engagement with the carding device as necessary.

What is claimed is:

1. A carding device for artificial teeth comprising a base, a plate carried by the base, studs for detachably engaging with the teeth carried by the base and projected through the plate, tongues resiliently ass0- ciated with the plate for exercising a constant pressure upon the teeth to hold the same yieldably engaged with the studs.

2. A carding device for artificial teeth comprising a base, a plate associated with the base and having a plurality of pairs of tongues resiliently connected thereto, studs carried by the base and extended through the plate and between the tongues for slidably and removably engaging the teeth When engaged with the tongues, said tongues exerting a constant pressure upon the teeth memes to hold the same against accidental disengagement from the studs.

3. A carding device for artificial teeth comprising a base, a metallic plate asso ciated with the base, tongues resiliently connected with the plate, means for detachably and slidably connecting the teeth With the plate, said tongues being adapted to yieldably engage the teeth, as and for the purpose set forth.

In testimony whereof I aflix my signature.
